This invention relates to composition shingles, and has for its object providing a method for making an improved type of composition shingle. The invention also '5 consists in providing an improved shingle, whether or not made according to my method, which. is in general the shape ,of

of the shingle which I provide, will be apconsist of a single thickness of felt, 17, which preferably has been impregnated in an ordiparent-from a consideration of the follow ing drawings and accompanying description thereof.

21 and 22 illustrate how these and similar shinglesmay be assembled.

The type of shingle illustrated in Figs. 1 to {L is formed by cutting from the strip of shingle material, in any suitable manner, individual shingles 15 which have one edge' materially longer than the opposite edge. The first step in the process is to crimp these shingles so'as to form corrugations16 therein, these corrugations being materially greater near the wide end than at the other end, so asto leave the outline of the shingle f substantially in the form of a parallelogram.

However, it is to be understood that the shape of the. outline of the shingle is not a material feature of my invention.-

he shingle, when so cutand formed, may

nary manner with asphalt or other suitable material. The shingles after being crimped are then coated, on the upper sui face-with asphalt 18 or other suitable material, and in so coating, the asphalt accumulates at the points 19, filling in more or less the corrugations at these points, especially at the end of. the shingle. The shingle is then coated with granulated mineral, such as the granullated slate 20, and this also tends to accumulate in the corrugations, at the points 21,. so .80 that the corrugations, or valleys between the ridges, particularly at the ends of the shingles, are substantially filled with asphalt and slate,-the upper surface of .thisedgr beingnearly level. Q i This method of forming the shingles thus provides for a very thick edge at the lower end of the shingle, this edge being the lower edge when the shingles are on the roof as indicated in Fig. 7, and thus the edge and the. shingle for some distance upwardly. ismuch stiffer than ordinarily, and the danger of being bent upward by the actionof' theweather or otherwise is substantially eliminated. This methodof forming the shingles also produces a very thick exposed edge;- which gives a distinctive and-tile-like appearance to the roof. Furthermore, the corrugations on the under side of the shingle.

provide air cells or spaces between the upper side, particularly at the lower edges, and, if desired, over the lap portion of the shingles which materially'increase the insulation properties of the roof.

A'somewhat modified rocess of forming these shingles is indicate by Fig. 5. I In this .case the strips of shingle material are impregnated and coated with asphalt and granulated slate or other suitable materials in any suitable or ordinary manner before be--' ing cut into individual shin les. The shin gles are then cut and crimpe as hereinabove explained,'and they are then coated on the shingle, with a coat of asphalt 25, which is sufiiciently thick to fill in the grooves 26 so that the upper surface is more or less level. On this surface-is then sprinkled a coat of mineral 27 which thus forms a coat similar to the ordinary coat of mineral on composition, or so much as may be desired.

tion shingles. It' will be understood, however, that this extra coat of asphalt and mineral may be over the entire upper surface of the shingle or may cover merely the la porn case of this type of shingle, the thickness of the exposed edge is increased over that of the type of Fig. 4, and the shingle is proportionally stifier and more definite indesigm,

plying the asphaltto the corrugated lower 'edge of the shingles so that it runs overthe edges and forms beads or a filler in the grooves on the .under side' of the shingle, as

indicated in Fig. 6, which is a sectional view. of the end immediately back of the slate 33v which also runs over the end ofthe felt. 1n thiscase the shingles consist of a layer of impregnated felt 30, coats of asphalt 28 and 29 on each side of the felt, and t e eoat ofmineral 32 which may be originally placed on the strip of shingle material. In addition there .the final coat of mineral 33.

are the additional coats of asphalt 31, and This 'mineral also,fif suitablyapplied, will adhere to the coat of asphalt on the end of the shingles and also to the beads on the lower side as indirated in the left hand end of the-fi e.

F ig. 7 shows one way of assemb ing these shingles,particularly the shingles illustrated in Figs. 4 and 5. But it is to be understood thatthese shingles may :be assembled in any suitable or ordinary manner. When assembled as indicated the roof is thoroughly protected from the weather, and a minlmum amount of shingle material is used, as the lap? ping on the side edges may be much less than normal owing to the nesting; together of the edge corrugations as. indicated. The ram cannot driven upwardly over the corrugations, and even if so it would need to pass back and over another corrugation before it could reach the roof. This method of assembling is possible notonly because of the cor rugations fwhich 'prevent leakage. but also because of the increased stiflness of the shin- A further step in my process consists in ap-.

gle, which prevents deformation thereof un der stress ofthe weather or otherwise.

Figs. 8 and 9 illustrate a modification of these shin les.. These shingles are cut fromv sheets in t e form of rectangle sheets 23, and these sheets are fluted or crimped longitudinally uniformly all the way across from end to end, forming corrugated sheets 34. One end of each of these sheets is then processed as hereinabove described, and shown in Figs. 4, 5, or 6, and the shingles may-then be laid as shown in gles are coated after being crimped about one third of their length so that the lap portion 35 has the corrugations on the upper surface substantially filled in level.

" Figs. 10 to-12 inclusive illustrate a modified type of shingle 36 which is cut fromthe sheet, as indicated in Fig. 10, and when cut, before being processed, is as indicated in Fig. 11. In this case the crimping is limited to what is the lower edge of the shingle and is sufficient merely to roduce a shin le with a contour as indlcate in Fig. 12.- size of the wings 40 it is apparent that the thickness of the shingle at the lower edge may be made as much as desired. These wings 4O- are produced by cutting ofi the corners 41 of the adjacent shingles. The material cut from the corners 41 is of no value in protecting the roof as this portion is entirely covered by other shingles. These shingles of Figs. 10 to 12 may processed as hereinabove described or in any other suitablemanner.

Figs. 13 to 16 inclusive illustrate another with reference to the other shingles, or in any other suitable manner. These "strip shingles may be assembled on the roof asindicated in Fig. 16, or in any other suitable manner. By 'assembling as indicated, the processed edges.

46 are positioned flush with the edges 47 of the underlying shingles, so that, at this edge the shingles are of double thickness. and the It will therefore be seen that I- have,'by my improved process, provided an improved type-of shingle whichmay be very quickly and conveniently laid on the roof, as in each case there are portions of the shingle which provide positioning means for laying the shingles. In case of the shingles offlFig. 7 thecorrugations at once determine the- Fig. -7. Preferably these shiny varying the distinctiveness of the edge is materially amamount of side lap of the shingles, and in 7 case of the shingles of Fig. 16, the position may be'exactly determined by placingthe lower edges 46, as described, flushwith the edge 47 of the underlying shingle and at the center of the recess 48. And in each case the .stitfness of the exposed edge of the shingle insures its clinging closely at all times to the roof, and the corrugations provide air spaces for greater insulation. And also the process lends itself to the formation of shingles which may be almost any desired jecting or shank portions 52 and 53 are fluted so as to ultimately make the sides of the recesses substantially parallel, as is shown by the respective Figs. 18 and 20. Also, in case of, the shingle 50, the entire shingle is fluted opposite the recesses 54, parallel and uniform transverse corrugations 55 being made therein, so that the recesses are narrowed by the.

fluting. One object of these transverse corrugations 55, is to improve the appearance of the shingle and also to provide more eflicient lapping means. These shingles are laid, as indicated in Fig. 22, with the ends lapping, preferably with two corrugatlons meeting. The end recesses or, notches 56 are of such length that, by lapping until the edge 57 of one shingle registers with the edge 58 of the adjacent shingle, the recesses at the lap ping ends will be the same-length as the recesses 54.

The shingle 51 when first cut has st1ll narrower recesses, as these shingles are not fluted transversely opposite the recesses.

The shanks 53, however, are fluted so as to produce recesses with parallel sides. These shingles are preferably laid as indicated in Fig. 21, with the edge 60 of one shingle abutting with the edge 61 of the adjacent shingle.

Although I have herein, and particularly I in the following claims, referred toasphalt as a suitable substance for coating the shingles, yet it is to 'be understood that any other suitable substance may be used, and particularly any bituminous compound.

I claim as my invention:

1. A method of forming shingles consisting in cutting from sheets of shingle material individual pieces, each piece having one edge materially longer-than the opposite edge, and in then crimping the long edge so that it is substantially the same length across as is the main bodv of the shingle.

2. A shingle having one end substantially flat, and the other end corrugated, with the corrugations extending inwardly towards the said flat end and decreasing in size as said flat end is approached, a coat of asphalt on one side of the corrugated end, and .a coat of granulated mineral on the coat of asphalt,

the said coats being thicker in the groovesv than on the ridges.

3. A shingle having one end substantially flat, and the other end corrugated, with the corrugations extending inwardly towards the said flat end and decreasing in size as said flat end is approached, a coat of asphalt on one side of the corrugated end, and a coat of granulated mineral on the coat of asphalt,

the said coats being thicker in the grooves than on the ridges, and extending entirely over the edge, the entire edge being substantially smooth.

In testimony whereof, I hereunto set my hand.
